柱面全景图单点投影及配准拼接算法

摘要

The image-based panoramic technology not only makes up for the deficiency of the geometry-based rending techniques,such as the modeling difficulty and the rendering tardiness ,but also can up to photo-realism .The key technology of panoramic is the panorama image registration and image fusion. On the basis of the projection principle of cylindrical panorama, this paper shows the projection arithmetic of the cylindrical panorama, and then realies an effective corner graphic feature extraction which is created by using SIFT arithmetic.%基十图像的全景图技术不仅可以弥补几何绘制技术建模难,渲染慢的问题,而且可以达到照片级的真实感.全景图的关键技术是图像的配准和图像融合技术.本文针对柱形全景图的投影原理,给出了柱形全景图投影算法,并在此基础上利用SIFT算法,实现了图形特征角点的有效提取.
